ABRAHAM: SOLOD, OF WORCESTER, MASSACHUSETTS.

DRIER FOR DRYING COTTON, WOOL, BAGS, 8w.

Application filed February 28, 1917.

To all whom it may concern:

Be it known that I, ABRAHAM SOLOI), a subject of Russia, residing at lVorcester, in the county of l/Vorcester and State of Massachusetts, U. S. A., have invented certain new and useful Improvements in Driers for Drying Cotton, Wool, Rags, &c., of which the following is a specification.

My invention relates to a drier for drying cotton, wool, rags, etc., and the object of my invention is to provide an improved drier of the class referred to.

My invention consists in certain novel features of construction, and combination of parts of a drier of the class referred to, as will be hereinafter described.

Referring to the drawings Figure 1 is a plan, and sectional view of a drier, and of a heating apparatus embodying my improvements, showing some of the parts broken away.

Fig. 2 is a longitudinal section, on line 2, 2, Fig. 1, looking in the direction of arrow a, same figure; the heating apparatus is not shown in this figure.

Fig. 3 is an end view of the drier cylinder looking in the direction of arrow 7), Fig. 2; the stand at the end of the cylinder is not shown.

Fig. 4 is an end view of the drier cylinder looking in the direction of arrow 0, Fig. 2.

In the accompanying drawings, 1 is a hot air chamber, 2 is a supply pipe from the boiler, not shown, leading to a series of pipes 3 within the hot air chamber 1, and 4 is a return pipe to the boiler. 5 is a blower, suitably operated, and by means of which hot air is forced through the pipe 6 and into the pipe 7, which is preferably of rectangular shape, as shown in Figs. 3, and 4, and is provided with a series of holes or perforations for the hot air to pass through, as shown at 7 in Fig. 2. The pipe 7 is, in this instance, rigidly supported at each end by two arms 8, 8, and 9, 9, see Fig. 2, which are secured to the stands 10, and 11, one at each end of the drier.

12 is a hollow cylinder, which is rotatably mounted, in this instance on three sets of rolls 13, 14, and 15. There are two rolls in each set, as shown in Figs. 3, and 4. The rolls 13, 14, and 15 are mounted on two shafts 16, and 17, the rolls 13, and 14 being loose on said shafts in this instance, and the rolls 15 tight on said shafts. The shafts 16, and 17 are mounted in stands 18, located Specification of Letters Patent.

Serial No. 151,419.

under the cylinder 12, see Fig. 2, in this instance there are three stands 18. On the shaft 17, shown in Fig. 1, is fast a gear 19, which meshes with and is driven by a gear 20, fast on a shaft 21, which carries a belt pulley 22, which is driven by a belt 23, from a belt pulley 24, fast on a driven shaft 25, see Fig. 1.

A sprocket chain 26, shown in Fig. 1, connects the shafts 16, and 17 through sprocket wheels 27, and 28, fast on said shafts, so that the shaft 16 is driven from the shaft 17. .A revolving motion of the shafts 16, and 17, through the rolls 15 fast thereon, causes the revolution of the cylinder 12, supported on the three sets of rolls 13, 14, and 15.

The cylinder 12 is of large size, ordinarily about twenty feet long, and seven feet in diameter, and extends in an inclined position, from its receiving end to its discharging end, as shown in Fig. 2. The cylinder 12 is preferably made of sheet metal, and has in this instance on its outer side three annular rings or collars 12, which are recessed or grooved on their periphery to leave a flange or projection. The rings or collars 12 rest upon the sets of rolls 13, 14, and 15. On the inside of the cylinder 12, and extending in the direction of its length, is a series of plates or strips 12, which extend around the inner side of the cylinder 12, in this instance, eight in number, shown in Figs. 3, and 4. These strips extend inwardly and act to carry the material, such as cotton, wool, or rags, around within the cylinder, to cause the material to fall upon the hot air pipe 7.

At the receiving end of the cylinder 12, there is a flange 12", shown in Fig. 4, which acts to hold the material within the cylinder, and at the discharging end there is a flange 12, shown in Fig. 3, which acts to hold the material within the cylinder.

A metal band 29 extends around the open end of the cylinder 12, at its receiving end, and is attached at one edge, to the frame or stand 10, as shown in Fig. 2, and extends at its other edge under a flanged collar 30 secured on the cylinder 12. A metal band 31 extends around the discharging end of the cylinder 12, and is secured at one edge to the frame or stand 11, see Fig. 1, and extends at its other edge under a flanged collar 32 securedon the cylinder 12. By means of the bands 29, and 31, the cylinder 12 is made air tight.

At the receiving end of the cylinder 12 is arranged a carrier 33, which is suitably mounted and operated, and may be in the form of an endless belt, upon which the cot ton, wool, or rags to be dried are placed, and automatically carried into the cylinder 12 at its receiving end. The carrier 33 may be driven by means of two sprocket wheels 34, and a sprocket chain 35, as shown in Fig. 2. The carrier'or belt 33 ismoved in a direction at right angles to the rotary motion of the cylinder 12. I

At the discharging end of the cylinder 12 is' arranged a carrier 36, which is suitably mounted and operated, and may consist of an endless belt upon which the dried cotton, Wool, or rags are deposited, as they pass out ofthe open end of'the cylinder.

Th'ecarrier or belt 36 has a movement in a direction corresponding to the direction of movement of the cylinder 12.

From the above description in connection with the drawings the operation of my improved drier for cotton, wool, or rags will be readily understood by those skilled in the art;

Hot air is forced into the perforated pipe 7 extending throughthe cylinder 12, at one side thereof, by means of the blower 5 forcing the air from the hot air chamber 1. The

cylinder 12 has a revolving motioncommuv nicated thereto through the rolls 13, let, and 1 5, and the shafts16,and 17, carrying said rolls, and driven by the mechanism shown in the drawings, and above described. The cot ton, wool, or rags are placed on the carrier 33, and are carried or fedinto the op'enend of the cylinder 12, and the longitudinally extending bars or strips 12 on'the inner surface of the cylinder 12, carry the cotton, wool, or rags around within the cylinder, and the hot air from the'pipe 7 will act on said cotton, wool, or rags, to dry the same, and said cotton, wool, or rags, by the revolving motion of the cylinder 12, and by the inclined position'of'said cylinder, are carried toward the discharging end of the cylinder and deposited on the carrier 36, and are carried off to be'deposited in a suitable receptacle, not'sh'own, all as will be readily understood by those skilled in the art.

It will be understood thatthe' details of construction of my improvements in a drier for cotton, wool, or rags may be varied if desired.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is 1. A drier for dryingcotton, Wool, rags, etc, comprising a rotary cylinder, extendin' in an inclined position, and mounted on rolls, and means for driving said rolls, and a carrier at one end for carrying the material into said cylinder, and acarrier at the other e'ndto receive the material from said cylinder, a hot air chamber, a perforated pipe within the cylinder at one side thereof, and means for forcingthe air fronrthe hot air chamber into said pipe.

2. A drier for drying cotton,'woo'l, rags, etc, comprising a rotary cylinder, extending in an inclined position, and mounted on rolls, and means for driving said rolls,"and a: carrier at one end for carrying the material into said cylinder, and a carrier at the other end to receive the m'aterialfrom said cylinder, a hot air chamber, a perforated pipe Within the cylinder at one side thereof, and means for forcing the air from the hot air chamber into said pipe.
